I think patience is a virtue with the Saga RRP.
Case in point: Back in the good 'ol days (2007) Dark Horse produced a limited edition RRP of Umbrella Academy Apocalypse Suite #1 (limited to 1,000 copies). I don't have data on what raw copies went for when they first hit the market, but GPA will show you what the first 9.8 slabs went for. If memory serves, it was somewhere around $300. Once the market for these things matured, the average price fell back to the $150-$200 range. People see "limited edition" and freak out because they don't want to miss out on it, but believe me when I say they will be available later. I've managed to secure 12 copies of the UA book in a little over 2 years (6 raw, 5 CGC 9.8, 1 CGC 9.9).
Granted, the Saga RRP has half the print run, but copies will be available at a more reasonable price once all the hype dies down.
